Name:	dblClickCommand
Class:	Command
Command-Line Switch:	-dblclickcommand



  

  
Specifies a Tcl command procedure which is called when an item is double
      clicked. Typically this occurs when mouse button 1 is double clicked over
      an item. Selection policy does not matter.






Name:	height
Class:	Height
Command-Line Switch:	-height



  

  
Specifies the height of the scrolled list box as an entire unit. The value
      may be specified in any of the forms acceptable to Tk_GetPixels.
      Any additional space needed to display the other components such as
      labels, margins, and scrollbars force the listbox to be compressed. A
      value of zero along with the same value for the width causes the value
      given for the visibleitems option to be applied which administers geometry
      constraints in a different manner. The default height is zero.






Name:	hscrollMode
Class:	ScrollMode
Command-Line Switch:	-hscrollmode



  

  
Specifies the the display mode to be used for the horizontal scrollbar:
      static, dynamic, or none. In static mode, the scroll bar is
      displayed at all times. Dynamic mode displays the scroll bar as required,
      and none disables the scroll bar display. The default is static.






Name:	sbWidth
Class:	Width
Command-Line Switch:	-sbwidth



  

  
Specifies the width of the scrollbar in any of the forms acceptable to
      Tk_GetPixels. The default width is 15 pixels..






Name:	scrollMargin
Class:	Margin
Command-Line Switch:	-scrollmargin



  

  
Specifies the distance between the listbox and scrollbar in any of the
      forms acceptable to Tk_GetPixels. The default is 3 pixels.






Name:	selectionCommand
Class:	Command
Command-Line Switch:	-selectioncommand



  

  
Specifies a Tcl command procedure which is called when an item is
      selected. Selection policy does not matter.






Name:	state
Class:	State
Command-Line Switch:	-state



  

  
Specifies one of two states for the listbox: normal or
      disabled. If the listbox is disabled then selection is ignored. The
      default is normal.






Name:	textBackground
Class:	Background
Command-Line Switch -textbackground



  

  
Specifies the background color for the listbox. This allows the background
      within the listbox to be different from the normal background color.






Name:	textFont
Class:	Font
Command-Line Switch:	-textfont



  

  
Specifies the font to be used for text in the listbox. This allows for the
      font associated with text internal to the scrolled listbox to be different
      than the font for labels.






Name:	visibleitems
Class:	VisibleItems
Command-Line Switch:	-visibleitems



  

  
Specifies the widthxheight in characters and lines for the listbox. This
      option is only administered if the width and height options are both set
      to zero, otherwise they take precedence. The default value is 20x10. With
      the visibleitems option engaged, geometry constraints are maintained only
      on the listbox. The size of the other components such as labels, margins,
      and scroll bars, are additive and independent, effecting the overall size
      of the scrolled list box. In contrast, should the width and height options
      have non zero values, they are applied to the scrolled list box as a
      whole. The listbox is compressed or expanded to maintain the geometry
      constraints.






Name:	vscrollMode
Class:	ScrollMode
Command-Line Switch:	-vscrollmode



  

  
Specifies the the display mode to be used for the vertical scrollbar:
      static, dynamic, or none. In static mode, the scroll bar is
      displayed at all times. Dynamic mode displays the scroll bar as required,
      and none disables the scroll bar display. The default is static.






Name:	width
Class:	Width
Command-Line Switch:	-width



  

  
Specifies the width of the scrolled list box as an entire unit. The value
      may be specified in any of the forms acceptable to Tk_GetPixels.
      Any additional space needed to display the other components such as
      labels, margins, and scrollbars force the listbox to be compressed. A
      value of zero along with the same value for the height causes the value
      given for the visibleitems option to be applied which administers geometry
      constraints in a different manner. The default width is zero.
    
    

    

  










The iwidgets::scrolledlistbox command creates a scrolled
    listbox with additional options to manage horizontal and vertical
    scrollbars. This includes options to control which scrollbars are displayed
    and the method, i.e. statically or dynamically.










The iwidgets::scrolledlistbox command creates a new Tcl
    command whose name is pathName. This command may be used to invoke
    various operations on the widget. It has the following general form:




pathName option ?arg arg ...?




Option and the args determine the exact behavior of
    the command.


Many of the widget commands for a scrolledlistbox take as one
    argument an indicator of which entry of the list box to operate on. These
    indicators are called indexes and may be specified in any of the
    following forms:



  

  
Specifies the element as a numerical index, where 0 corresponds to the
      first element in the listbox.

  

  
Indicates the element that has the location cursor. This element will be
      displayed with an underline when the listbox has the keyboard focus, and
      it is specified with the activate widget command.

  

  
Indicates the anchor point for the selection, which is set with the
      selection anchor widget command.

  

  
Indicates the end of the listbox. For some commands this means just after
      the last element; for other commands it means the last element.

  
@x,y

  
Indicates the element that covers the point in the listbox window
      specified by x and y (in pixel coordinates). If no element
      covers that point, then the closest element to that point is used.

  

  
If the index doesn't satisfy one of the above forms then this form is
      used. Pattern is pattern-matched against the items in the list box,
      in order from the top down, until a matching entry is found. The rules of
      Tcl_StringMatch are used.




The following widget commands are possible for scrolledlistbox
    widgets:










activate	bbox	curselection	delete
get	index	insert	itemconfigure
nearest	scan	see	selection
size	xview	yview


See the "listbox" manual entry for details on the
    associated methods.











  

  
Returns the current value of the configuration option given by
      option. Option may have any of the values accepted by the
      iwidgets::scrolledlistbox command.

  

  
Clears the listbox of all items.

  

  
Query or modify the configuration options of the widget. If no
      option is specified, returns a list describing all of the available
      options for pathName (see Tk_ConfigureInfo for information
      on the format of this list). If option is specified with no
      value, then the command returns a list describing the one named
      option (this list will be identical to the corresponding sublist of the
      value returned if no option is specified). If one or more
      option-value pairs are specified, then the command modifies the
      given widget option(s) to have the given value(s); in this case the
      command returns an empty string. Option may have any of the values
      accepted by the iwidgets::scrolledlistbox command.

  

  
Returns the contents of the listbox element indicated by the current
      selection indexes. Short cut version of get and curselection command
      combination.

  

  
Justifies the list contents via teh scroll bars in one of four directions:
      left, right, top, or bottom.

  

  
Returns the number of items currently selected in the list.

  

  
Sort the current list in any of the forms accepted by Tcl's lsort command.
      Also accepts either ascending or descending order.
